Smugglers pair banned HBM with weak server chips to slip memory into China

The trick is structural, not technical. Export control rules look at the performance of the server processor, not at the other components attached to it. So a slow chip can carry fast memory past the line, Tom's Hardware reported on 3 November, citing The Information.

The smuggler runs a chip design firm that builds low-performing processors. Those chips fall under both US and South Korean controls. The boards are then fitted with HBM from Samsung and SK hynix, memory that on its own is banned for export to China.

The route is not clean. The assemblies land in Hong Kong and cross into Shenzhen in the luggage of commuters who make the trip daily, according to the same account. In workshops there, technicians heat the boards to soften the solder. They lift the memory chips off and throw the rest away. The failure rate is high. The price of HBM makes the work worth it.

Tom's Hardware's story lands the same day as a second report about the same gap in the rules, this one from the buyer side of the market. Nvidia has told some cloud customers to take on less business from Chinese companies, The Information reported, citing three people familiar with the matter. The instruction was passed on verbally through sales reps and regional teams, according to the Financial Times.

A directive with no paper trail

According to The Decoder's account on 3 November, the guidance is not mandatory. It applies to future contracts rather than existing deals. Cloud providers, including Nvidia-backed neoclouds, are also being asked to disclose who the end users are.

Why it matters: US export controls restrict chip shipments but generally do not cover remote access through cloud services. A Chinese AI developer can rent compute capacity in a data centre abroad and reach advanced Nvidia hardware without importing anything. The Decoder notes that US authorities had been looking into Chinese AI companies reaching such chips through foreign data centres. That followed allegations involving Moonshot AI, the developer behind the Kimi chatbot.

On the same day, CnEVPost reported that Tesla China's October wholesale sales came to 67,829 vehicles, according to preliminary data from the China Passenger Car Association released on Tuesday. That is up 10.30% year on year but down 28.88% from September, the lowest monthly level since February, when the figure was 58,599. Cumulative wholesale sales in the first 10 months reached 810,889, up 21.42% year on year. The preliminary data did not break out domestic sales and exports, so the split behind October's number is not public.

Note the divergence from the wider market. The CPCA estimates nationwide passenger NEV wholesale sales at 1.8 million units in October, up 12% year on year and 8% from September. Tesla's yearly growth trailed that, and its monthly move went the other way.

"The total quota is limited, so each company will not receive a large export allocation. All the automakers are currently working to secure their share," one person familiar with the matter told Cailian, as quoted by CnEVPost.

That quote sits at the centre of the European story. Several Chinese automakers have travelled to Beijing recently for talks with regulators on quotas for hybrid vehicle exports to the EU, Cailian reported on Monday, citing multiple people familiar with the matter. The talks came less than a month after the two sides announced an understanding on hybrid trade. CnEVPost, which carried the report on 2 November, says the report did not name the automakers involved, the volumes each was seeking, or the criteria for allocation.

The numbers behind the talks come from elsewhere. China's Ministry of Commerce said on 12 October that the sides had agreed an arrangement allowing growth from the 302,000 hybrid vehicles the EU imported from China in 2025. Bloomberg reported on 11 October, citing a proposal document it had seen, that the quota would be set at 350,000 vehicles in the first year. It would rise 6% annually from the second year and stay in place for four years. Those measures could take effect as early as 1 December and cover both HEVs and PHEVs, according to that report. EU trade commissioner Maros Sefcovic said on 9 October that the understanding included halving Chinese HEV and PHEV exports to the EU but did not specify the baseline. That leaves the two descriptions hard to reconcile.

The supply side, in numbers

Chery Group, which reported on Sunday, offers a sense of how much Chinese carmakers now depend on markets outside China. It sold 295,934 vehicles in October, up 5.25% year on year, with 140,893 NEVs, a record and the seventh consecutive month above 100,000. Exports reached 200,618, up 58.67% and about 68% of the monthly total, the third time this year overseas sales passed 200,000, CnEVPost reported on 1 November. In the first 10 months, exports totalled 1,751,766, up 64.8%.

Electric heavy trucks tell a similar story of a market moving faster than policy. Electric trucks made up 50.3% of all heavy trucks sold in China in September, 33,100 units, up 37% year on year while the overall heavy-truck market shrank 21%, according to Electrek on 2 November. Through the first nine months of 2026, China sold 226,400 electric heavy trucks, up 64%, for a 38.1% share. Eleven government bodies had set a target of 40% new-energy heavy-truck sales by 2030. The monthly figure passed it four years early. China's diesel demand is on track to fall by about 230,000 barrels per day this year, Electrek reports, with battery and natural gas trucks doing most of the work.

Toyota's China problem is the mirror image. Lexus will build its next electric SUV in Jinshan, Shanghai, for sale in 2027, the brand's first vehicle made in China in over two decades, Electrek reported on 2 November. Capacity is around 1,000 units per month in 2027, ramping to tens of thousands in 2028. Toyota sold just over 1.05 million vehicles in China in the first nine months of 2026, 18.9% fewer than a year earlier. Its sales fell nearly 20% last month, the eighth consecutive month of decline.

On the capital markets, the mood has turned. Reuters reported that China's STAR50 index of AI and semiconductor companies fell 40% over four months, wiping out $480 billion in market value. CleanTechnica relayed that figure on 1 November along with a quote from Beijing fund manager Dong Baozhen: "The stock market later evolved into a speculative crazy bull. And now we see the bubble bursting." CleanTechnica also notes that shares in robotics company Unitree have halved since its August IPO and that chipmaker CXMT has lost more than a quarter of its value in a month. Treat the causal claims in that piece as commentary; the index move is the number to hold on to.

None of these threads run in one direction. On 3 November, Tom's Hardware documented a control regime being walked around at the level of a single circuit board. The Decoder documented a company asking customers to self-police a gap the rules do not close. Beijing, meanwhile, is drafting export curbs of its own on AI and other technologies, a proposal that has run through Reuters and specialist trade coverage since late October. The pattern here is not controls versus free trade. It is controls everywhere, written loosely enough that the burden lands on whoever interprets them first.
